Description

As a certified reference material (CRM), 1,2-di-(9Z,12Z,15Z-octadecatrienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinolenoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:3 PG 474943-20-9 PG(18:3(9Z,12Z,15Z)/18:3(9Z,12Z,15Z)) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1,2-di-(9Z,12Z,15Z-octadecatrienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinolenoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:3 PG 474943-20-9 PG(18:3(9Z,12Z,15Z)/18:3(9Z,12Z,15Z)) (CAS 474943-20-9) is a high-purity analytical reference standard with the molecular formula C42H70O10PNa and a molecular weight of 788.98 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,2-di-(9Z,12Z,15Z-octadecatrienoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dilinolenoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:3 PG 474943-20-9 PG(18:3(9Z,12Z,15Z)/18:3(9Z,12Z,15Z)) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 788.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
